My brother got rid of his Gamo Hunter for the same reason.
not consistant with any pellet he tried. My beeman is finniky
about what it likes to shoot. The Gold plated Gamo pellets
are deadly out of it but i tried some with the little steel ball
in the nose and I literally missed an old car hood 4 out
of 5 shots at 30 yards.. no joke, completely missed!
1 hit, 2 shot low, 2 shot high. Not sure what happened
with those things. They shoot fine out of an old Daisy
Springer I have?
